Connecting to ASA

Connections to ASA databases are made via the supplied jConnect JDBC Driver, which is contained in the jconn2.jar file stored in the Sybase\Shared\jConnect-5_5 directory after installation. To access this JAR file from your application, simply include jconn2.jar in your classpath, as you would any other Java archive. This archive includes Sybase's 100% pure JDBC driver. A separate driver is included for applications that want to connect to an RDBMS using a JDBC-ODBC bridge. As with any JDBC application, the first step is to obtain a java.sql.Connection object that can be used to query the database. The following code snippet illustrates how this would be done:

Properties props = new Properties();
props.put( "user", "admin" );
props.put( "password", "123456" );
Class.forName( "com.sybase.jdbc.SybDriver" ).newInstance();
String URL = "jdbc:sybase:Tds:localhost";
Connection conn = DriverManager.getConnection( URL , props );

The connection above was obtained using a "ServiceName" parameter, which must be of the following syntax:

jdbc:sybase:Tds:machine-name:port-number?ServiceName=DBN

Typecasting the com.sybase.jdbc.SybDriver class allows us to also use the SybDriver class' setRemotePassword() method to pass additional parameters.
